Insights
Silent myocardial infarction (SMI) is more common in older adults. This case report highlights SMI in a COVID-19 patient, emphasizing the need for cardiac evaluation in all COVID-19 cases, especially the elderly.
Area of Science:
- Cardiology
- Infectious Diseases
- Geriatrics
Background:
- Silent myocardial infarction (SMI) is increasingly recognized in elderly individuals with cardiovascular risk factors.
- The prevalence of SMI in patients with COVID-19 remains largely unknown.
- COVID-19 is associated with cardiovascular complications, but silent presentations are not well-documented.
Observation:
- A 77-year-old male with COVID-19 pneumonia presented with diabetic ketoacidosis and multiorgan failure.
- The patient experienced a silent ST-segment elevation myocardial infarction (STEMI) without typical anginal symptoms.
- This represents the first reported case of SMI in a COVID-19 patient.
Findings:
- Cardiac catheterization revealed ostial right coronary artery stenosis.
- A drug-eluting stent was successfully placed following a specialized safety protocol.
- The patient was discharged in stable condition to an extended-care facility.
Implications:
- COVID-19 patients, particularly the elderly, require cardiac evaluation for acute myocardial infarction, even in the absence of symptoms.
- Prompt diagnosis and intervention for myocardial infarction in COVID-19 patients, using appropriate safety measures, can be life-saving.
- This case underscores the importance of considering silent myocardial infarction in the differential diagnosis of COVID-19 presentations.
Abstract:
Silent myocardial infarction or unrecognized myocardial infarction has increased prevalence in elderly population with increased cardiovascular risk factors. However, its prevalence in COVID-19 patients is not well-known. A 77-year-old Caucasian male with COVID-19 pneumonia, presented with silent ST-segment elevation myocardial infarction, diabetic ketoacidosis and multiorgan failure. He underwent cardiac catheterization and drug eluting stent placement in the ostial right coronary artery with safety protocol. He was discharged to extended-care-facility in stable condition. This is a first case report of silent ST-segment elevation myocardial infarction in a patient presenting with COVID-19. In patients with COVID-19, acute myocardial infarction should be ruled out even when asymptomatic, especially in older patients. Prompt intervention using safety protocol is life-saving.
